U.S. utilities continue to send workers to Puerto Rico to help restore that country’s electricity and rebuild its power infrastructure, a task that continues more than four months after back-to-back hurricanes left nearly all of the island in the dark. The Puerto Rican government this week said 83% of the island’s generation capacity has been […]

A control system that smooths out inter-area oscillations—a problem affecting power systems connected by relatively weak tie lines—has been successfully demonstrated by researchers from Sandia National Laboratories and Montana Tech University. The system that uses smart grid technology could allow utilities to push more power through transmission lines, possibly nixing the need for new transmission […]

Utilities across the U.S. are aware of beneficial electrification (BE) programs, but wide adoption has been held up by uncertainty about their potential and broader role in the evolving regulated utility

Unmanned aerial systems—drones—have quickly found their place in the power sector. But as the industry moves out of test cases and experiments, and into full implementation of drones, it is facing a whole

A leading-edge operations center opens in New York The New York Power Authority (NYPA) has taken a huge step forward in increasing the efficiency of its operations with the opening of its new Integrated Smart Operations Center (iSOC), which harnesses the capabilities of state-of-the-art digitization technologies. The center, located in White Plains, N.Y., was officially […]

When is a D+ grade acceptable? The answer should be never. But that’s the state of the U.S. power grid according to the 2017 infrastructure report card issued by the American Society for Civil Engineers (ASCE). And the impact of this year’s catastrophic hurricane season only reinforced its vulnerability. Given the billions of dollars of […]

GE and Exelon announced a multi-year agreement to deploy GE’s portfolio of Predix software solutions across the energy company’s six electric utilities to further enhance reliability and efficient service to its more than 10 million customers. Exelon’s six utilities will use these advanced analytics to further strengthen transmission and delivery systems. POWER Executive Editor Aaron […]

Siemens has launched a new direct-current (DC) transmission system for alternating current (AC) grids of between 30 kV and 150 kV. The medium-voltage system that can bridge distances of up to 125 miles is designed to help grid entities handle ever-growing volumes of power fed into the distribution system from distributed and renewable power. The […]

Recently, two epic hurricanes—Harvey and Irma—struck North America with extremely destructive force. Harvey first made landfall in the U.S. near Rockport, Texas, about 30 miles northeast of Corpus Christi

Researchers at the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) have developed a unique large-scale power converter that can swiftly switch between multiple energy sources to help
